The game launched in North America and Europe on October 27 and 23, respectively. Since then, players have logged over 6.6 million collective hours playing online across over 64 million play sessions.

Now, the team is offering new downloadable cars for the game alongside the milestone, as a commemoration of sorts.

Forza 3, which seeks to hybridize the sim genre with some more accessible arcade elements, already contains more than 400 vehicles, and now users can buy a holiday car pack for 400 Microsoft Points.

Included in the 10-car pack are a Ferrari 458 Italia, a Nissan GT-R Spec V, and a Mercedes SLR Stirling Moss, among others. Microsoft says another car pack will launch early next year, timed alongside the North American International Auto Show.
